XSLT - (Runtime) Message
About
The message is part of the console, not of the XSLT transformation output.
Syntax
<xsl:template match="/ARTICLE/SECT/SECT/SECT">
<xsl:message terminate="yes">
Error: Sections can only be nested 2 deep.
</xsl:message>
</xsl:template>
where:
- the terminate=yes clause causes the transformation process to stop after the message is generated.
